What You Need to Know About Hiring a Roofer in Cardiff
Your roof is your first line of defence against Welsh weather, so getting the right person for the job matters. Whether you're dealing with a leak, missing tiles, or planning a full replacement, knowing what to expect takes the stress out of the process.
This guide walks you through finding a qualified roofer in Cardiff, understanding costs, and asking the right questions. We'll cover the accreditations that matter, what's typical for roofs in the Cardiff area, and how to avoid common pitfalls.
Most jobs need at least three quotes. Don't just pick the cheapest — experience and guarantees are worth paying for. A good roofer will turn up on time, protect your property during work, and leave the site clean.
Typical Roof Repair and Replacement Costs in Cardiff
Costs depend on what needs doing. Here's what you're likely to pay:
Repairs and maintenance:
- Fixing a single leak or replacing a few slipped tiles: £150-£400
- Chimney flashing repair: £200-£600
- Gutter cleaning and minor repairs: £100-£300
- Roof inspection and report: £150-£250
Larger jobs:
- Re-tiling a small section (under 50 sqm): £2,000-£5,000
- Full slate or tile roof replacement (100-150 sqm): £8,000-£18,000
- Flat roof replacement: £4,000-£12,000
- New pitched roof with structural work: £15,000-£35,000
Prices depend on roof pitch, access, materials chosen, and whether structural repairs are needed. Cardiff's older stock often means more complexity. Always ask if quotes include scaffolding, disposal, and warranty. Some jobs need building regulation approval — your roofer should flag this.
Accreditations and Qualifications That Matter
Look for these credentials when vetting a roofer:
NFRC (National Federation of Roofing Contractors): This is the main trade body for roofers in the UK. Members sign up to a code of conduct, carry insurance, and must demonstrate competence. Check the NFRC register online to verify membership.
RoofCERT: An independent certification scheme for roofing contractors. RoofCERT-registered firms have been audited and must maintain standards. It's less common than NFRC but respected.
CSCS card (Construction Skills Certification Scheme): Operatives should carry a valid CSCS card — it shows they've passed health and safety tests.
Insurance: Ask for proof of public liability (at least £6 million) and employers' liability if they have staff. This protects you if something goes wrong.
Building Regulation Approval: For major work, the roofer should be registered with a competent person scheme or your local council. Don't skip this — it affects insurance and resale value.
Roofing Issues Specific to Cardiff
Cardiff's housing mix creates particular challenges. The city has plenty of Victorian and Edwardian terraces with original slate roofs — beautiful but aging. These need specialist knowledge; slate repair isn't the same as tile work, and you may need matching reclaimed slate.
Post-war semis and detached homes often have clay tiles that can suffer from frost damage in Welsh winters. The wet climate means moss and lichen growth is common — regular cleaning prevents water pooling.
Flat roofs on 1960s-70s properties are notorious. Felt deteriorates quickly in our damp climate; many Cardiff homeowners are switching to modern EPDM or TPO membranes for better longevity.
Cardiff Council's Building Control team can advise on Listed building regulations if your property is protected. The Welsh Weather Centre reports that Cardiff gets around 1,100mm of rain annually — above the UK average — so drainage and ventilation are critical. A local roofer familiar with Cardiff's housing stock and climate will anticipate these issues.
How to Find and Hire a Qualified Roofer
Start by getting personal recommendations from neighbours or friends who've had work done recently. Word-of-mouth is gold.
Use Best Trades Wales to search local roofers. Check their profiles, read reviews, and note their accreditations.
Get three quotes minimum. A good quote should be in writing, itemise materials and labour, include a timeline, and state what warranty covers. Avoid anyone reluctant to provide this detail.
During the quote visit, notice whether they inspect properly — climbing onto the roof or using binoculars to check condition. Someone who quotes over the phone without looking isn't thorough.
Ask for references from jobs done in the last two years. Contact at least one — it takes ten minutes and saves headaches.
Agree payment terms in writing. Never pay upfront in full. A typical arrangement is a small deposit (10-20%), payment on completion, or for large jobs, staged payments. Get a written contract covering scope, cost, insurance, and dispute resolution.
Questions to Ask Before Booking
Don't be shy asking these:
About the roofer:
- How long have you been trading?
- Are you NFRC registered? Can you prove it?
- What's your public liability insurance limit?
- Can you provide three recent references?
About the work:
- Will you get building regulation approval if needed?
- What warranty do you provide on labour and materials?
- Do you arrange scaffolding, or is that extra?
- How will you protect the interior if there's heavy rain during work?
- When can you start, and how long will it take?
- Will you dispose of old materials?
- Do you guarantee the roof won't leak for a set period?
About the quote:
- Is this price fixed, or can it change?
- What's not included in the quote?
- Do you charge for the inspection/quote?
- Will you provide a breakdown of labour and materials?
If someone brushes off questions or can't give straight answers, move on.
